For the oilfields in east China with long-term water injection development

the water injection efficiency is gradually reduced due to the developed high water consumption strip in reservoir. In order to define the influence factors of development of the high water consumption strip

taking northern Shuanghe block in Nanyang as the research object

the influences of injection rate

permeability ratio

permeability variation coefficient and formation coefficient on the development of high water consumption strip have been analyzed respectively. Combined with orthogonal experiment

the relative influence level of the four factors is compared. The results show that high permeability

low injection rate

high permeability variation coefficient and high permeability ratio are more likely to cause the problems. With a certain formation coefficient and injection amount

high permeability is in major. Through the orthogonal test

the permeability variation coefficient influences most

followed by permeability ratio and formation coefficient

and the injection rate influences least. This study provides some reference for the adjustment in the later stage of oilfield production.
